Abstract

We describe the beneficial contribution of fetal MRI in evaluating the site and extent of airway compression by the dilated pulmonary arteries in a case of Tetralogy of Fallot absent pulmonary valve syndrome (TOFAPVS) diagnosed by fetal echocardiography at 20 weeks gestation age. Although, the fetal echocardiography is an adequate tool to establish the diagnosis of TOFAPVS which can be done accurately as early as 20 weeks gestation; fetal MRI should be considered as an adjuvant tool to evaluate the site and extent of tracheo-bronchial tree compression in patients with TOFAPVS.
